Now, Magic: The Gathering 's Final Fantasy crossover set has revealed its answer to Final Fantasy 7 's romance question, and I think Wizards of the Coast found the perfect solution
Legends like Graaz, Unstoppable Juggernaut who turns all your creatures into 5/3 Juggernauts, or the new variant of everyones favorite Phyrexian Angel, Atraxa, Grand Unifier, which gives us a Niv-Mizzet Reborn effect that looks at cards types instead of colors
If the target creature is an illegal target as Harvestrite Host's ability tries to resolve, it won't resolve and none of its effects will happen
So far in 2020, we've been averaging about one per month (and if you go back to the initial release in December, we've actually had 13 individual drops in three months, making the average closer to four drops per month since the series was announced), although the average is somewhat complicated by how you count themes that come with multiple drops, like the original Theros Gods during Worlds in February (technically, the Gods were five individual but related drops, although there is an argument for counting them as one big drop since buying all of the drops together was an option)
